What a powerful lesson! I typically use this at the end of Spanish 2 when we discuss holidays and disasters.
Jueves was written about the Madrid metro bombings in 2004. I give the students the sheet lyrics up, instructing them not to flip the page to the article. We listen to the song as they fill in the lyrics. We then discuss the partial meaning. Without telling them what the song is about, I instruct them to flip it over and skim the article answering the main W questions (Who? What? When? Where? Why? How Many?). On some of these they must make inferences, so it's challenging but leads to a great class discussion. There are some great music videos on youtube and vimeo that can be paired with the lesson, some including actual video footage from the security cameras the day of the bombing and playing on the romantic storyline of the song.
I've always had great responses to this lesson and it has been very impactful. I hope it is for your students too!
